Reference Pacemakers Opens New Window Reference Opens New Window are small electrical devices that help control the timing of your heartbeat.

A pacemaker is implanted under the skin of your chest wall. The pacemaker's wires are passed through a vein into the chambers of your heart. The pacemaker sends out small electrical pulses that keep your heart from beating too slowly.

To be sure that your device is working right, you will need to have it checked regularly. Pacemakers can stop working because of loose or broken wires or other problems. Your doctor also will make sure that your pacemaker settings are right for what your body needs.
